Oops! Honestly SamTherapy I'm really not that bothered about it. I was just curious that's all and j thought I'd ask the question in case it was something  I was doing wrong rather than just the way it is. Poser is a whole new world to me and I'm just trying to get my bearings and understand the whys and wherefores of how things works. To be honest I hardly  know my texture maps from my elbow in poser at the moment, but though  I have  M4 and a bunch of morphs muscle maps and so on  I can't see anything other than the basic texture anywhere so I guess that's all I have.
I actually only came to notice the  blur because I was trying to get rid of the hair altogether on a character I was playing around with!

So yes,not stressing, I'm really enjoying this program, I've been buried in photoshop for the past umpteen years so It's good to get out to pastures new.
Thanks all for your explanations,much appreciated.
